9. Solder Profiles
Composition of the solder ball: Sn 95.5%, Ag 4.0%, Cu 0.5%
Typical Lead-Free Re-flow Solder Profile
Key features of the profile:
Initial Ramp = 1-2.5°C/sec to 175°C±25°C equilibrium
Equilibrium time = 60 to 180 seconds
8
Chongqing Jinou Science & Technology Development Co., Ltd
Ramp to Maximum temperature (250°C) = 3°C/sec max.
Time above liquidus temperature (217°C): 45-90 seconds
Device absolute maximum reflow temperature: 260°C
Devices will withstand the specified profile. Lead-free devices will withstand up to three
reflows to a maximum temperature of 260°C.
Notes:They need to be baked prior to mounting.
10. Guide for Antenna Radiation
In order to achieve longest communication range, please keep the area surrounding
antenna free of grounding or metal housing.
